POST   /api/auth/logout
GET    /api/auth/me

Jobs

GET    /api/jobs
GET    /api/jobs/:id
POST   /api/jobs
PUT    /api/jobs/:id
DELETE /api/jobs/:id

Applications

POST   /api/applications
GET    /api/applications
GET    /api/applications/:id
PUT    /api/applications/:id

Users

GET    /api/users
GET    /api/users/:id
PUT    /api/users/:id
